Beam Angle The Beam angle of light source describes how light is distributed from the source of illumination onto a targeted area.
Ingress Protection Ingress protection ratings or IP ratings, refers to the level of protection offered by an electrical equipment against solids and liquids, where the first digit from left side describe the resistance of the enclosure to solids, while the right side digit describe the resistance to water.
Color Temperature CCT Color temperature is a way to describe the light appearance provided by a light source where it is conventionally expressed in the degrees of Kelvins (K) on a scale from 1,000 to 10,000.
Lumens Lumens (LM) is a measure of the brightness emitted from light source . in another meaning it describes how much light you are getting from the light source. The higher lumen means higher brightness.
Color Rendering Index Color Rendering Index (Ra) is a quantitative measure of the ability of a light source to reveal the colors of various objects faithfully in comparison with an ideal or natural light source measured in a scale from 0 to 100, where Ra below 80 is considered as poor while Ra higher than 80 is considered good color rendering.
